Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/podo/design-agent-skills --skill excalidraw-diagram- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads excalidraw-diagram automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.

Heads-up
- Requires: uv (Python) and Playwright Chromium for the mandatory render-and-validate loop (
cd .claude/skills/excalidraw-diagram/references && uv sync && uv run playwright install chromium); The skill hard-codes the project path.claude/skills/excalidraw-diagram/references, so install it at project scope (not -g) for the render step to work - License: no LICENSE file in the repository
Invoke after install
- Skill name:
excalidraw-diagram - Trigger phrases: "excalidraw diagram", "excalidraw", "diagram from description"
What it does
Generates .excalidraw JSON files from natural language descriptions. Diagrams are designed to "argue visually": shapes mirror the concept they represent (fan-outs for one-to-many, timelines for sequences) and include evidence artifacts such as real code snippets or payloads. A render-view-fix loop (Playwright renders the file to PNG, the agent looks at it and fixes layout problems) validates each diagram before delivery. All colors and brand styles live in references/color-palette.md, so editing that one file re-skins every diagram. Output is an editable .excalidraw file.
When NOT to use
- Quick ideation sketches where no uv and Playwright toolchain is wanted — use
hand-drawn-diagrams(lighter weight) orexcalidraw-agents365 - Wireframes of screens rather than concept diagrams — use
